FAST UWB Survey

FAST UWB Survey


The FAST UWB Survey (fast_uwb) published its results in papers published from 2019 to 2021 with a total of 20 new pulsars discovered. It detected a grand total of 3 pulsars. The fastest pulsar discovered was J1717+4308A with a period of 3.15972 milliseconds and the slowest pulsar was J2053+4718 with a period of 4.91038 seconds. The smallest pulsar dispersion measure was J0021-0909 with a DM of 25.2 pc/cc and the largest pulsar dispersion measure was J2053+4718 with a DM of 331.3 pc/cc. There were a total of 2689 pulsars known before the first discovery was published. This survey increased the total amount of known pulsars by 1.0%.

There were 4 papers written about the discoveries of this survey: The first pulsar discovered by FAST, PSR J1926-0652: A Pulsar with Interesting Emission Properties Discovered at FAST, An in-depth investigation of 11 pulsars discovered by FAST, The FAST Discovery of an Eclipsing Binary Millisecond Pulsar in the Globular Cluster M92 (NGC 6341).
